Bitwise operators in Arithmetic instruction in c

Hello friends,

Today I am going to tell you what is bitwise operators in Arithmetic instruction in c?   and how it performs its function in Arithmetic instruction in c programming language. In this post i will tell you how many types of bitwise operators in c programming and its function also.

In previous post we will discuss about what is athematic instruction in very detail so, please see previous post to reach the previous post please click on athematic instruction in c programming it appears green. If you do not read the previous post then you can not able to understand what is going on in this post and you leave this website so, please read my previous post.

Now let’s start todays topic which is bitwise operators

What are bitwise operators

Bitwise operator is used to manipulate BIT level data. This operator is used for shifting from right to left and left to right bit. The bitwise operator does not apply to float and double data types.

 

Computer only works on 0 and 1. The full form of Bit is a binary digit which is 0 and 1. The bitwise operator is calculated at 0 and 1. Whenever we manipulate the decimal number by bitwise operator, the processor first converts it to the form of 0 and 1 and then calculates it.

Now if you understand what is bitwise operators then now let’s know type of bitwise operators

How many types of bitwise operators in Arithmetic instruction in c?

Basically, there are six type of bitwise operators which are given below

 

Description	operators
Bitwise - And	&
Bitwise - Or	|
Bitwise - Xor	^
Bitwise - Not	~
Right - shift	>>
left - shift	<<

 

Now we study type of bitwise operators in very detail so let’s start with first type of bitwise operators

Behavior of & operator

0 & 0 = 0

0 & 1 = 0

1 & 0 = 0

1 & 1 = 1

If one operand is 0 and second operand is also 0 then the result is also 0.

If one operand is 0 and second operand is 1 then the result is also 0.

If one operand is 1 and second operand is also 0 then the result is also 0.

If one operand is 1 and second operand is also 1 then the result is also 1.

If you understand the behavior of & operators then now let’s take an example for better understanding of function of & operators in athematic instruction in c programming

Example:1

Int x;

X = 23 & 56;

Now we first convert this number into binary number then we solve this according to & behavior

23 = 10111

56 = 111000

We have to wright this in 16 bits because integer constant consumes 16 bits so we use 0 to make this number 16 bit

23 = 0000 0000 0001 0111

56 = 0000 0000 0011 1000

Now we can perform & operators

23 = 0000 0000 0001 0111

56 = 0000 0000 0011 1000

16 = 0000 0000 0001 0000

The output screen shows 16 answer

Behavior of “Or” operator

0 | 0 = 0

0 | 1 = 1

1 | 0 = 1

1 | 1 = 1

If one operand is 0 and second operand is also 0 then the result is also 0.

If one operand is 0 and second operand is 1 then the result is 1.

If one operand is 1 and second operand is also 0 then the result is also 1.

If one operand is 1 and second operand is also 1 then the result is also 1

If you understand the behavior of ‘|’ operators then now let’s take an example for better understanding of function of ‘|’ operators in athematic instruction in c programming

Example:2

Int x;

X = 23 | 56;

23 = 0000 0000 0001 0111

56 = 0000 0000 0011 1000

63 = 0000 0000 0011 1111

The output screen shows 63 answer

Behavior of “^” operator

0 ^ 0 = 0

1 ^ 0 = 1

0 ^ 1 = 1

1 ^ 1 = 0

‘Xor’ says if both numbers are same then the result is 0 and if both numbers are not same then the result is 1

If you understand the behavior of ‘^’ operators then now let’s take an example for better understanding of function of ‘^’ operators in athematic instruction in c programming

Example:3

Int x;

X = 23 | 56;

23 = 0000 0000 0001 0111

56 = 0000 0000 0011 1000

47 = 0000 0000 0010 1111

The output screen shows 47 answer

Now let’s know about the function of right shift operator

Function of right shift operator

In this operator, we shift the binary number into right side by using 0.

Take an example for better understanding

Example:4

Int x;

X = 56 >> 2;

56 = 0000 0000 0011 1000

We add left side = 00

The number will be

14 = 0000 0000 0000 1110

 

We right 2 so we shift 56 right side by using two 0. If we write any number at the place of 2 for example, we wright 4 then we add four 0 from the left side.

Hope you understand 

For this we add two 0 in left side and through this, the number shift right side

Hence, the output screen shows 14 answer.

Function of left shift operator

In this operator, we shift the binary number into left side by using 0.

Take an example for better understanding

Example:5

Int x;

X = 56 << 3;

56 = 0000 0000 0011 1000

We add right side = 000

The number will be

448 = 0000 0001 1100 0000

 

We right 3 so we shift 56 right side by using three 0. If we write any number at the place of 3 for example, we wright 4 then we add four 0 from the right side.

Hope you understand 

For this we add three 0 in right side and through this, the number shift left side

Hence, the output screen shows 448 answer.

Hope you understand the bitwise operators. If you have any quarry about bitwise operator then you can comment me on comment box.
